Nothing too special, I just decided to take an Altergeist deck I made and started to swap out cards until it's now at around $61, which I'm happy with.
You can swap out super poly with dark ruler no more, ghost ogre with ash blossom, appointer with solemn strike, pot of duality with pot of prosperity, remove terraforming, metaverse, and Emulelf for infinite impermanence, heavy storm duster with cosmic cyclone, and add in apollousa, accesscode, and underworld goddess in the extra. Nibiru and evenly matched are also good alternatives for the side deck.
